Microsoft showed off a number of its latest research projects at the Silicon Valley TechFair research fair in Mountain View on April 17.

Among the featured projects — some of which the company had touted previously, others not — were a couple of big data- and analytics-focused ones.

Naiad on Azure, described as a "rich, interactive cloud analytics project," is a .Net-based data-analysis project. Using Naiad, analysts can develop applications locally before deploying it to the cloud, according to the project description.

Researchers also showed off a big data project focused on monitoring urban air quality, as well as "WaveFour," which is a social-analytics platform for businesses. "Tempe" is another Microsoft Research project aimed at exploiting faster machine learning.

At the fair, Microsoft officials also highlighted contributions the Microsoft Research team made to recently introduced products, including the Cortana personal digital assistant baked into Windows Phone 8.1, as well as the shape-writing technology that is part of the enhanced Word Flow keyboard in Windows Phone 8.1.
